   Hydrological models are simplified representation of the real basin system, which helps to assess basin function in response to different inputs and better understanding of hydrological processes. The HEC-HMS model is one of the most important hydrological models for Flood estimating volumes and discharge in watersheds. In this research, the HEC-HMS hydrologic model was used to simulate the ...

Simulation of the runoff-rainfall process in forest lands is essential for land management. In this research, a hydrologic modelling system (HEC-HMS) and artificial neural network (ANN) were applied to simulate rainfall-runoff (RRP) Kasilian watershed with an area 68 square kilometres. The HMS model was performed using secondary data rainfall discharge at climatology hydrometric stations, Soil ...

This work focused on the collection and preparation of data required for hydrological modelling Beht catchment area, which covers an area 4560 km 2 with a perimeter 414 km, by combining various spatial technologies, in particular geographical information systems (GIS), remote sensing, digital terrain models (DTM), order to prepare used flood forecasting. The methodology consists, at first, auto...

estimation of parameters of a hydrologic model is undertaken using a procedure called “calibration” in order to obtain predictions as close as possible to observed values. this study aimed to use the particle swarm optimization (pso) algorithm for automatic calibration of the hec-hms hydrologic model, which includes a library of different event-based models for simulating the rainfall-runoff pr...

هـدف این مطالعه، شبیه­سازی رواناب حاصل از ذوب بـرف در حوضه­ی شـهرچای، با استفاده از دو مدل SRM و HEC-HMS است. بدین منظور، ابتدا با وارد کردن داده­های پوشش برف، متغیرهای هواشناختی و پارامترهای لازم به مدلSRM ، رواناب ناشی از ذوب برف شبیه­سازی شد. در مدل HEC-HMS نیز پس از ایجاد مدل حوضه با نرم‌افزار HEC-GeoHMS در محیطGIS  و ایجاد مدل هواشناختی و واردکردن پارامترهای لازم مانند تلفات، روندیابی و ذو...

The most important problem in estimating floods is the lack of sufficient statistics and consequently the lack of evaluation of the appropriate amount of flow. One of the flood estimation methods in these basins is the use of hydrological modeling. In this study, Shahbahram river flood modeling was performed with Nazmkan hydrometric station located in Kohkiluyeh Boyer-Ahmad province with HEC-HM...

The present study is an attempt to assess the impacts of climate change on water resources of the river basins of India which have immense importance in domestic, industrial agricultural and hydropower scenario. A distributed hydrological model developed from HEC-HMS was used on the Indian river basins using the projected daily precipitation and temperature data for the continuous daily range f...
